(28, 65, 55)-Net over F₄ — Digital

Digital (28, 65, 55)-net over F₄, using

t-expansion [i] based on digital (26, 65, 55)-net over F₄, using
- net from sequence [i] based on digital (26, 54)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 26 and N(F) ≥ 55, using
    - Drinfeld modules of rank 1 [i]

(28, 65, 333)-Net in Base 4 — Upper bound on s

There is no (28, 65, 334)-net in base 4, because

1 times m-reduction [i] would yield (28, 64, 334)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 343 835882 600772 261508 042544 544393 974296 > 4⁶⁴ [i]
